In this study, considering that the tension variations affect the quality of fabrics and weaving performance or efficiency, the effect of well density, well number, weave type and measuring region of warp tension on warp tension have been investigated. For this purpose, the fabrics were woven in seven different pattern constructions with four different well densities using two different well in count. Warp tensions have been measured under running conditions of the loom. Hence, the relationship between the tension and weaving parameters determined has been given on the base of this study. Statistical analysis was made by using Design-Expert 6.0.1 package programme. The effect of the factors, weave type, well number, well density and measuring region of warp tension, has been investigated by using varyans and regression analysis. The regression equations have been determined for all the weave types. It is concluded that weave type, measuring region, well density, well number, weave type x measuring region, measuring region x well number factors effect the warp tension statistically significant level (p<0.001).
